EPITHELIAL COCCYGEAL PASSAGE EXCISION METHOD Russian patent published in 2024 - IPC A61B17/00 A61B17/04 A61M27/00 

FIELD: medicine; surgery; coloproctology.

SUBSTANCE: epithelial coccygeal duct (ECC) is excised with all branches within healthy tissues with the formation of a fusiform skin wound, shifted laterally into the area of greater distribution of the passages from the midline of the body, and in the lower part extending to the buttocks. Full-thickness subcutaneous flaps are mobilized by transection of connective tissue adhesions between skin and sacral fascia. Formed cavity is drained with a tube delivered through the counteropening in the area of the upper angle of the wound. Flaps are displaced relative to each other along the vertical axis to form an S-shaped wound, which in the lower part is displaced on the buttocks area by suturing located in the frontal plane, parallel to the skin with subsequent layer-by-layer closure of the remaining wound above the drainage in the upward direction with interrupted sutures.

EFFECT: method provides reducing the incidence of postoperative wound complications, the frequency of recurrences and the length of complete wound healing due to reduced depth of intergluteal fold, absence of funnel-shaped retraction in lower angle of wound.
